Octomom in Plane Fight with '3rd Rock' Star

Flying on a plane next to 12 screaming kids is enough to drive anyone insane -- and that's exactly what set Kristen Johnston off last night ... and the 12 kids belonged to Octomom!

Nadya Suleman was flying back from New York City last night and her and the brood took up most of the business class section of the plane. The flight was delayed for more than two hours and Nadya tried to silence the kids -- to no avail.

The crying babies annoyed the "3rd Rock from the Sun" star so much, she marched over to Nadya and told her keep it down.
